th all 'whom it may concern lle it linown that ll, Renn-nr d. Sinnen, a citizen ot fUanada, and a resident ot the 'city and county ot dan Francisco, 'State of Cali tornia, have invented a certain new and usegtul Wire-Binding Machine, ot which the following is a specification.

rll`he invention relates to machines for wire hindingboxes, bunches oi? shocks, etc.

An .object of the invention'is to provide a machine tor passing a wire' around a box or bunch oit shoolrs, drawing the wire tight and twisting the ends oil the wire.

Another object of the invention is to provide a machine which automatically accomplishes theoperations ot passing the wire around the bundle, drawing it tight, twisting the ends, and cutting the wire.

Another object ot the invention is to provide means for alining and compressing the hunch of shoolrs heiore they are'hound together.

A further object ot the invention is to provide an improved mechanism for forming the wire into a loop.

'llhe invention possesses other advantageous features, some ot which, with the toregoing, will be set A.torth at length in the tollowing description, where ll shall outf line in lull, that form ot the invention whichli have selected for illustration in the drawings accompanying and forming partei the present specication. lln said drawlngs l have shown one specilic 'torni or my generic invention, but it is to he understood that l do'not limit myself to such torni, since the invention as expressed in the claims may be embodied in a plurality of forms.

Referring to said drawings.:

and cut the wire adjacent the twisted portion. 'llhe machine comprises a suitable trame 2 upon which the various mechanisms which coperatie to produce the desired result are mounted. 'lhe trame is provided with extended portions 3 which form tables or supports for the box or bundle ot shools, andl with an extension A overlying the hunch or shoolrs 5. 'lhe upper portion ot the trame is 'termed ot two parte spaced apart laterally from each other, so that n passage is formed ior'the tree movement oil the wire-carrying shuttle. lldonnted on each trame part are a plurality ol sproclrets d, i", 8, 9, l2, l, the sprockets ot each pair being axially alined, and engaging each group ot sprockets is van endless chain ld, there heingV two parallel spaced chains. .lhe sprocln ets lis-9 are carried on an adjustable crosshead l5, so that the tension oit the chain may he adjusted when desired. Connecting the two chains and preferably rotatably mounted vin oppcsitely-disposed soclrets carried thereby, is a cross-har i6. upon the center of which is mounted the wire-carrying shuttle i7. The shuttle comprises an elon gated hollow member through which the wire 18 passes andit is provided with clamping blocks 19 which prevent the wire from becoming disengaged from the shuttle. rll'he supply ot wire is carried on a suitable reel placed in the rear of the machine and the wire is carried up between the two spaced frame parts and threaded into the shuttle, so that the end of the wire projects from the forward end of the shuttle. As the chains 14 are driven, the shuttle travels from the upper forward edge of the.. bunch of titi shocks around the three sides of the bunch,

to the lowerforward edge of the bunch.

Arranged at the front of the frame is a vertically movable hollow frame or gate 21 which is engaged and guided by the grooved rollers 22 journaled on the frame 2. The gate is movable upwardly and downwardly with periods of rest at the top and bottom of its reach, the movements and rests cooperating with other movements of the com'- plete mechanism. Mounted in the upper portion of the gate is a rotatable head 28, which is provided with means for gripping the end of the wire and drawing it down across the frontface of the bunch of shooks when the gate is lowered. Attached to or formed integral with the head is a sprocket 24 which is engaged by an endless chain 25 running over sprockets 26 disposed at the four corners of the frame. Movement of the chain causes rotation of the head and by stopping the rotation of the head while the chain is being driven, the gate is raised or lowered. Meshi'ng with the chain 25 is a driving sprocket 27 which is rotated in opposite directions in time with the operation of the machine, causing the raising and lowering of the gate and the operation of the head at the proper times.

Formed on the rotatable head is a jaw or projection 28 which coperates with va spring-pressed jaw 29 rotatably mounted on the head. Secured to the spring-pressed jaw 29 is an arm 31 which is arranged to contact with a latch 82 mounted on the gate 21. When the sprocket 27 is rotated in a direction to move the chain'25 upwardly at the sprocket, the chain is moved relatively to the gate and causes a rotation of the head in a clockwise direction (Fig. 6), bringing Vthe arm 31 into contact with the latch 32.

This stops the rotative movement of the jaw 29, while the head `continues to rotate, causing the jaws 28-29 to be opened. A stop 33 on the head then contacts with the arm 31, stopping the rotation of the head, so that further movement of the sprocket 27 causes the gate to be raised, the position of the head during the upward movement of the gate being shown in Fig. 6.

Before the gate reaches its upper position, the shuttle 17 has been moved to its position above the bunch of shooks as shown in dotted lines in Fig. 1, and the end of the wire 18 projects from the shuttle and lies in the path of the open jaws 28-29, so 4that when the gate reaches its upper position, the end of the wire 18 lies between the jaws. The direction of rotation of the sprocket 27 is then reversed, and due to the pressure of the spring coperating with jaw 29, the head is rotated for a short distance in a counter-clockwise direction (Fig. 7), bringing the jaw 28 against jaw 29 and clamping the end of the wire. The'head is then prevented from rotating farther by a spring-pressed stop 34 mounted on the gate and engaging in a depression 35 in the periphery of the head. The stop and the depression have sloping sides, so that an increase in turning force on the head forces the stop out of engagement.

The head is provided with a sector-shaped slot 36 extending from the periphery to the center, and the slot is so disposed that its opening occurs at the lower part of the head, as the head moves downward. The upper cross bar of the gate is open below the center of the head, so that the slot opens into the space within the gate. Before the gate reaches its lower position, the shuttle has traveled to a position below and in front of the lower forward edge of the bunch of shooks, so that as the gate descends, thc head passes down over the wire, seating the wire at the base of the slot. The gate having reached its lowermost position, is halted, but the sprocket 27 continues to rotate, turning the head in a counter-cloclm'ise direc tion (Fig. 7) for several turns. The spring latch 32 has an inclined upper face, so that the arm 31 in moving around, pushes the latch 32 back at each revolution. This rotation of the head twists the ends of the wires together, firmly securing; them and binding the bunch of shocks.

After turning in a counter-clockwise direction for a sufficient number of turns to tightly twist the ends of the wires, the head is rotated for a short distance in the opposite direction, to cut the wire. Formed on the opposite end of the jaw 29 is a knife 37 and when the direction of rotation of the head is reversed, the arm 31 contacts with the latch 32, halting its movement, and the further movement of the head brings the slot under the knife and the wire is cut. This finishes one cycle of operations of the machine, and it is automatically stopped to permit the bound package to be removed and another package to be inserted, after which the machine is again set in operation.

Journaled in the frame of the machine is the drive shaft 38 which is connected to any desirable prime mover. Secured to the drive shaft is a gear 39 which meshes with a gear 41 mounted for rotation on the shaft 58. Loosely mounted on the shaft ,58 adjacent the gear 41 is a gear 42 from which the chains are driven. The sprockets 12 which drive the chains 14 are secured to the ends of shafts 43-44 which are driven from the shaft 48, through the sprockets 45-46 and the chains 47. The sprocket-s 12 are spaced .apart and are secured to the adjacent ends of the shafts 4B-44, so that an open space is provided between the sprockets to permit the shuttle to pass. The shaft 48 is driven from the gear 42 through the gears 51, 52 and the shaft 53. In the operation of the machine theshuttle stops in two positions, one its upper position, which occurs above the upper lll liti

llh

iront edge oi the bunchot ehoolrs and tivo, its lovver position, which occurs belovv the loner trent edge ot the bunch, and in mov ing from one position to the other it travels f around three sides el the bunch.

are provided for halting the movement oi the chalns when the shuttle reaches either' oit' 'these tivo stations and these means preise ably coiiperate with the gate-moving means,

so vthat the chains and gate move alternately.

Means are also provided i'or giving the vertically movable gate an intermittent motion, stopping it at the top and bottom and also tor producing the desired movement oi the head. Secured to the shalt 58 and arranged adjacent the gear il is a gear vvheel 59 `which is adapted to be connected to the*` gear Lil., so that they rotate together at certain portions oit' their revolutions. i Carried by the gear Wheel 59 is' a clutch member, comprising in this instance, an expanding band 62, which is disposed Within the flange.

the earn 65. 'lhe cam 65 in the band 62 is4 provided With an operating lever 66 and the cam in band 63 is provided with an operating lever 67. 'lhe levers are Varranged rto normally expand the bands, and means are.

provided tor engaging the leversto move them to contract the bands. The gear wheel is provided adjacent the end ot the lever 66 with av projection 96 to vvhich the lever is connected by a spring 97 which normally presses the lever away from the projection,

in which position oit the leverthe band 62 expanded. 0 'llhegear vvheel 59 is provided with an 1nternal segmental gear 69 and a segmental gear 69 ci lesser radius having 'exterior teeth, the gears beingl disposed so that they are brought intov action successively. 'lllie internal gear 68 coversan are ot approxlmately 180 and the external 'gear 69 an arc.

of less than 180, the end of one gear being preferably angularly spaced from the beginning of the other gear. 7l and arranged Within the gear Wheel is a 'pinion 72 adapted to mesh successively with the internal and external segmental gears. 'llhe sprocket '27 which drives the chain 25 on the gate is secured to shaft 7l, so that as the gear Wheel is rotated, the sprocket is rotated intermittently in opposite directions. rlhe expanding band 62 is operated twlce 1n 4eachrevolution of the gear wheel to release the gear Wheel from the driving gear 41 so that two periods of rest of the sprocket 27 are ltlleans he bands may be expanded in.

Secured to a shaft iprovided each revolution oi the pear wheel.. Arranged adjacent the gear ivieel and in position to be engaged by the lever 67 are latches 7tl--7fi, each having a seat 76 adapted to be engaged by the leveru llhe lever moves intothe seat and against the shoulder 76 and its motion is arrested, and the further movement oi the gear Wheel causes a movement oi the lever with respect to the gear wheel, turning the cam and contracting the band 62, 'lhis turtherrnovement ot' the gear wheel also compresses the spring' 97 and causes the projection 66 to enter the seat in the latch, lthereby holding the lever against movement in either direction and stopping rotation of the gear `wheel. When it is desired to start the gear Wheel again, the latch is disengaged troni the lever, the spring torcesthe lever around, moving the cam and expanding the band. rllhe latches '7B-7d are arranged so that they operate to stop rotation oi the sprocket 27 -vvhen the gate has been raised to its upper position and also immediately after the Wire has been cut.

rlhe latch 73 which operates to stop the rotation ot the gear Wheel alter the Wire has been out is subsequently released by the handle 9d.- llhen the latch y73 is released, the gate rises to its upper position, Where it is halted by engagement of the lever 66 vvith the latch 7l. Means are also provided whereby the arrival of the gate at its upper position releases .the lever 67 controlling the band 63, so that the chain driving gear d2 is rotated to move the shuttle from its upper to its lovver position., trrangedfto engage the lever 67 is a latch. 96, pivoted to the frame and operatively connected with a earn 99 secured to the gear Wheel 59. The cam is so rpositioned that vvhen the gear Wheel 59 reaches the position which corresponds to the upper position ot the gate, 'that the latch.

96 is raised. lihe gear 4t2 then rotates until the shuttle has moved to its lower position, when the lever 67 engages the latch 2h92, conn tracting the 4band 66 and releasing the gear ,t2 irornfthe drive gear ll. The latch 7l is operatively connected with a cam l03 secured to the gear 4t2 and this cam -is so placed that when the shuttle reaches its lower' position, the latch 7l is operated to release the lever 66 and the band 62 is expanded, causing gear vvheel'59 to rotate until the lever 66 is engaged by the latch 7 3, at which time, the Wire has been twisted and cut.

Means are provided for alining the stack of shocks and for compressing them during the binding operation. Slidably arranged in the trame at opposite sides thereof are tvvo pairs of horizontal, longitudinally disposed rods 107--108, each pair of which carries a vertical bar 109 which is disposed behind the bunch of shocks. The vertical bars are provided with screw-threaded sockets 'lli liti

ltltl ltlli lltl through which screw-threaded portions of the rods eXtend, so that rotation of the rods changes the setting of the vertical bars. In order that this settin may be readily accomplished, I' provi e each rod with a sprocket 111 and connect the sprockets with a chain 112. Pivoted to the frameand engaging each rod is al bell crank lever 113 which is connected at its other'end to a rod 114, which is in turn connected to the lever 115. The lever` 115 is provided with a roller 116 on its end which engages the cam 117 secured to the shaft 58, so that as the shaft rotates, the bars 109 are moved forward against the stack'of shooks, forcing them into alinement. lSecured toshaft 58 is a second cam 118, with which co erates a lever 119 pivoted to the frame. rranged at the upper part of the frame and to one side of the open center thereof, is a lever 121 to which the lever 119 is connected by the rod 122. Adjustably secured to the free end of the lever 121 is a presser foot 123, which, when the lever is depressed, bears against and compresses the stack of shooks. The cams 117 and 118 are so disposed with relation to'each other that the shook alining means is first brought into operation to straighten the stack of shooks and to shift the stack to proper position, after which the presser foot is brought into operation. The cam 118 isof such dimensions that pressure on the stack is maintained until after the wire binding is completed.

rEhe operation ofthe machine is as fol-- lows:

Infthe beginning, the shuttle 17 is at its upper station, the gate 21 is lowered, the

head 23 is in the position shown in Fig. 6,.

the lever 66 is inengagement with the latch 73, and lever 67 is in engagement with latch 98.` The bunch of shooks is then placed on the machine and the. handle 94 is moved to trip the latch 7 3, causing the gear wheel 59 to rotate (pinion 7 2 being in mesh with gear 69), and rotate the sprocket 27 in a clockwise direction, raising the gate to its top position. At this point lever 66 engages latch 74, stopping the gear wheel with the pinion out of mesh with gear 69 and causing the head to rotate slightly to grip the end of the wire projecting from the shuttle. Latch 98 is then raised, causing a movement of the chains, to draw the wire tightly around the three sides 0f the bunch, and then the shuttle is stopped by engagement of lever 67 with -latch 102. Latch 74 is then tripped and gear wheel 59 is again rotated, causing the gate to lower due to the engagement of pinion 72 withgear 68. When the gate reaches its lower position, the wire enters the groove in the head and then the head is rotated several times, tightly twisting the wire. The gear 68 then moves out of engagement with the pinion 72 and gear 69 moves into engagement, giving the head a short rotation in the opposite direction to cut the wire and then the lever 65 seats in the latch 73. At the' same time the latch 102 is operated by the cam' 99 and the shuttle moves back to and is stopped in its original position. The bound bunch of shocks is removed and the machine is in position to receive another bunch of shooks.
